One of the principal methods of protecting such a pipeline against local damage caused by impact loading is to provide the pipeline with an outer coating of reinforced concrete. However, it is acknowledged that there will be a limit to the ability of any structural concrete to absorb, without undue signs of distress, the energy resulting from a collision between the heavier types of trawl gear and a pipeline. When the limiting capacity of the concrete coating is being approached it may be then necessary to increase either the wall thickness of the steel pipe or alternatively trench the pipeline. This paper, which describes the preliminary assessment of the feasibility of developing a rational design procedure for the design of concrete coatings, discusses the practicality of optimising or enhancing the impact resistance of concrete coatings.
